My Vimproved. roll'su'pp'ort consists of a y which the roll of stationery 'is supported and which are held apart byspacer rods 7 andfS. Between these spacer rods are located the roll'bearings 9 and 10 which are mounted on VVthe'respective side bars and 6. Bearing 9 isa relatively stationary. bearing kwhile bearl ing f1() is-aXially movable'towardY yand away Vfrom 'bearing9, both bearings being'in axial V5o alignment to support the' roll of stationery yfrom theu rollrno'unted betweenthe bearings.

paperfweb `from the rollil4 i paper 4which may ybe hangingV from `the roll y 11 thereon asshown in Fig. 2. Bearing@ `is preferably formed of a-shallow cup,` lshaped yelement or disc which is yriveted 'or otherwise rigidly secured toa short spacer 412 extending from a side bar 5 to holdthe bearing away from/the side bar. Bearing is rirustr'oconi'cally cup-shaped and is v,se-y

-`A groove 17in spindle 18Jhas been provided to receive a latch 18 which is pivoted on the side of bar 6, so that the bearingy 10 may be lockedagainst inadvertent movement' away Roll 11 is yprovided with ka core 19 of tu# bular `materialpsuch as card board. 'In the Y' 'y ends of' this cardboard core flanged metal cup shaped;y caps 20 and 21 are pressed. These afford good interior bearing surfaces for the bearings 9k and lO so that the paper y y n roll may rotate easily and with a yuniform cation and illustrated 1n kthe accompany1ng drawings, in which:

It willbe seen that'theinterior roll core cap. diameters are larger than the diameters Of"5thetwo f1 bearings.. which .occupy them. This5 as shownin Fig.i 2, causes the roll to hang upon 'f the bearingsr soithat rotation ofthe'roll takes f f place Iby a slipping Or sliding action ofy the l' :roll caps 20 and 21on the topsof the beary `ings 9.and` 10.y Thisolf centerhangingoff frame having two Side v`bars 5 and 6 between theroll on itsmounting bearings produces s `a brakingaction on the roll Which keeps it fromunwinding through its own momentum orbeoause of the kweightof the*V webof the as it is drawn away. The brakingaction lis f rollk is large in diameter the braking action is greater and asit decreases in'diameter the ance imtil 'the 'r'oll is 'allunwoun'd.

braking action becomes less. This is of ma- 'terialadvantage in'preventing trouble from unwinding through the'weight of the paper webv hanging from the roll and causing its inertia of rotation to continue withoutassist- Y Naturally whenthe roll is large it would have much more inertia oi' movement 'to be overcome in theevent it vstarted to unwind, ence :the necessityfof morebraling action.

But', as the roll diameter decreases this mass i tion- 'whioh is 'alsoillustratedin. Fi'gfQ i'sthe inertia becomes less, hence the. necessity for' lessbraliing action. Thus the ve'lemei'it oi decreasing,` roll weight is advaiitageouslyyem- Dployed to give the roll the required degree `o'i braking action lasthe pap-'er used from it Another'marked advantage "et my construc- -use of ytheyfrustroconical"bearing 10.
